My daughters 1999 with 4 cylinder 2WD. When at a stop and in Drive or any forward gear there is severe shake or vibration. A lot of it coming with the steering wheel shaking rather violently. I thought perhaps it was motor mounts but my mechanic has ruled that out. Any other ideas? It does not do it in Park , Reverse or Neutral and my solution till now has been to simply slip it into Neutral at a stop and back into Drive when the light changes.
